The present device embodies an `arcuate clamp to lit the inner periphery ot the `telly F,and to engage some ot the spokes Svvhereby said clamp in engaging the telly and spokes will maintain itselt1 in place securely. As shdwnin Figs. 1 to il, inclusive, this clamp is divided longitudinally, and has the opposite .longitudinal side sections 10 and 1l. The side section 10 comprises the two arcuate parts 12 and 13, and, similarly, the section 1l comprises the two arcuate parts 14C and 15, such parts being stamped trom sheet metal or otherwise formed, and having their .adjacent ends overlapping, as atf16, for adoverlapping terminals ot the two parts there oli' are provided at those edges opposite the other sections, with llanges 18 extending at an `angle away troni the center ot the wheel to overlap one another and to also overlap the corresponding side of the telly. These flanges 18 of the two sections overlap one another at the opposite sides ot the telly,

`and bear against said sides ot the telly when the two sections are brought together. Flach flange 18 has a longitudinal series ot apertures 19, and the conipanlon flange 18 is provided at one end with a lug 2O to enter said notches or apertures, so that the apertures and lugs of the flanges ot each pair rinterengage mutually, as seen in Fig. n

This provides for the relativeadjust- ,'mentrof the parts of each section' of the clamp by separating said parts and shifting them longitudinally relatively to one another to the desired adjustment, and moving the flanges 18 together so that the, lugs 2() enter the respective apertures 19 to hold the parts in adjustment. The flanges 18 of each pairare clamped together. Thus,`the outmest flange 18 'has a longitudinal slot 21 through 'which' a screw 22 passes and said p Vscrew is threaded into the innermost flange whereby to clamp said flanges together. The screw when loosened enables the flanges to be separated forpurpose of adjustment, and the slot21'permits of the longitudinal adjustment of the parts. The parts of each section of the clamp are, thus adjusted longitudinally tocorrespond with the spacing of theouter ends of the spokes adjacent to the telly, and when this adjustment has once been made, the device can be applied to and l removed .from thewheel without further adjustment. This enables the device to be vapplied to various wheels, wherein the louter ends of the spokes are spaced different distances apart.

The parts, of the sections and 11 are provided at their opposite ends and opposite edges with apertured ears 23, and one flange 18 of each pair'is also provided with ,e a similar apertured `ear 24, and the tractionV chains or members which extend around the tire and across the tread thereof,l vhaving their terminals engaged with the ears 23, thus connecting said chains or members at their terminals to the opposite clamp sections 10 and 11.

In order to connect the sections of the clamp when they are brought together at the inner periphery of the felly, the parts 14 and 15 are provided at those edges adjalseries of notches 29, so that when the tongues of the section 10 are inserted Vthrough'the flanges 26, and the two sections 10 and 11 shifted longitudinally slightly, this will engage the flanges 26 in Yso the corresponding notches 29, thereby holding the two sections 10 and 11 together against separation. The series of notches 29 provide for-lateral adjustment to accommodate wheel fellies of different widths, as will be readily understood. A spring latch 30 ispivoted, as at 31, to one flange 26 and can be swung behind one of the tongues 28, as seen in Fig. 2, to hold the tongues ,in engagement with the flanges. The latch 30 has a lug 32 to spring into the corresponding slot 27 to prevent the latch from swinging out of locking position. This will prevent the unlocking of the two sections of the clamp, although said latch can be readily sprung manually out of engagement with the slot and tongue and then swung to releasing position, as seen in dotted lines in Fig. 1. Then, by shifting the sections of the clamp longitudinally relatively to one another, the notches 29 and flanges 26 are disengaged, and the sections can be readily separated, thereby withdrawing the tongues 28 from the slots 27. It is thus an easy matter to apply the device by passing the two sections of the clamp across the opposite sides of the tire bringing the chains or members 25 across the tread of the tire and the sections aie then moved together at the inner periphery of the f'elly, and when shifted longitudinally will be locked together. The latch 3() is then manipulated to prevent accident-al disconnection. The central notches or recesses 17 accommodate the intermediate spoke, while the end notches or recesses snugly receive the other spokes` as seen in Fig. 2, thereby snugly holding the clamp in place. Furthermore, the opposite edges of the parts of the clamp have ears 33 extending at an angle to overlap and bear against the opposite sides ot the telly to assist. in securely holding the device in place. Thus, the two sections ot the clamp are moved together laterally to fit and engage the folly, and to also engage the spokes with the parts of said sections located between three spokes, and the connecting means of the sections are also located between said spokes.

Figs. 5 and 6 illustrate a modification, wherein the clamp is designed for use between a pair of' spokes. The clamp comprises the two side sections 10 and 11, composed of the respective arcuate parts 1213, and 14f15 having their adjacent end portions overlapping, as at 16. The opposite ends of the parts have the notches or recesses 17 to receive and fit the two spokes. Longitudinal adjustment of' the section is obtained by a longitudinal series of apertures or notches 19 in the parts 12 and 14C', and the adjacent ends of the parts 13 and 15, repectively, have lugs 20 to engage in the apertures for maintaining the adjustments. The parts 13 and 15 have longitudinal slots 21 through which screws 22 extend, and said screws are threaded into the parts 12 and 14 for clamping the parts of the sections together. This adjustment is similar to the adjustment between the flanges 18 above described. The parts have the apertured ears 23 for the connection of the traction chains or members, and the parts 1&1 and incanta j through which the tongues ot the parts l2 and 13 moveivhen the tivo sections are brought together. the tongues 28 have notches 29 to more into engagement With the flanges 26. to hold the sections together and a spring latch 30" is also used heing pivoted, as at `31 to oneliange 26 to en-` gage the `corresponding tongue 28" and said latchfhasya ing-l2 to snap into the corresponding slot 27 similar to the latch 30 liereinhetore described.

'this device isapplied in practically the same manner as the device shown in Figs. 1, 2 and 3, and is somewhat more simple in conVVA struction in that it is only used between a pair ot spokes, instead ot engaging three spokes. j j A turther modification is shown in Fig. 7; Thus, the tongue 28 ot the section 10 which passes through the tlange 26 ot the section l1 has a series ot apertures 29 instead ot the notches and a key or pin 30 is inserted in one ot said apertures, to hold the sections together,` instead ot using the notches and latch as `hereinhetore described. llVith this arrangement, the sections are not sliitted longitudinally relatively to one another into engagement, hut are simplymoved together transversely and the key or pin 30 inserted into the proper aperture ot each tongue.
